[0026] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] Example 1

[0028] In a typical embodiment of the present invention, Figure 1 As shown, an energy-saving vehicle-mounted liquid rapid heating method is provided, comprising the following steps:

[0029] Get the current temperature of the liquid, set the heating temperature, and calculate the difference between the heating temperature and the current temperature of the liquid;

[0030] Determine the difference and the preset threshold value, when the difference is less than or equal to the preset threshold value, use the temperature rising module A to heat the liquid, when the difference is greater than the preset threshold value, use the temperature rising module B to heat the liquid; wherein the heat of the temperature rising module A comes from the non-power energy of the vehicle, and the heat of the temperature rising module B comes from the power energy of the vehicle;

[0031] The liquid reaching the heating temperature is discharged as required.

[0032] In this embodiment, the temperature increasing module A includes a heat exchanger, which is arranged in a liquid storage container and connected to an engine coolant pipeline. The heat exchanger recovers the heat of the vehicle engine and provides it to the vehicle liquid to be heated in the liquid storage container, and the vehicle liquid is heated by using the recovered heat of the engine. The heat dissipated by the engine will be absorbed by the coolant, and the temperature of the coolant will rise after absorbing the heat, and enter the heat exchanger in the liquid storage container, and the heat will be provided to the vehicle liquid through the heat exchanger. There are many small channels inside the heat exchanger, and the coolant and the liquid to be heated flow in their respective channels in the heat exchanger to transfer heat.

[0033] Alternatively, the temperature-raising module A includes a solar collector and a heat exchanger, wherein the solar collector is arranged on the top of the vehicle, and the heat exchanger is arranged in a liquid storage container. The solar collector and the heat exchanger are connected through a heat exchange medium pipeline, and the heat exchange medium is heated by absorbing the heat of sunlight by the solar collector, and the heat exchange medium heats the vehicle-borne liquid through the heat exchanger. The solar collector is composed of a transparent cover plate, a heat absorbing plate, a heat insulation layer and a shell. The transparent cover plate allows sunlight to penetrate into the interior of the collector, and the heat absorbing plate is usually a metal plate coated with a selective absorption coating, which can efficiently absorb the energy of sunlight and convert it into heat energy. The heat insulation layer reduces the loss of heat to the outside, and the shell plays a role of protection and support. The heat exchange medium flows in the pipeline in the heat absorbing plate, and the heat of sunlight absorbed by the heat absorbing plate is transferred to the heat exchange medium in the pipeline through heat conduction. The heat exchange medium enters the heat exchanger through the pipeline, and through the heat exchanger, the heat exchange medium provides the absorbed solar energy to the vehicle-borne liquid to be heated.

[0034] In this embodiment, the heat exchanger can use an S-shaped pipe with good thermal conductivity and be set in a liquid storage container. When the liquid is heated by the heat of the engine, the engine cooling medium flows in the heat exchanger. When the liquid is heated by solar energy, the heat exchange medium flows in the heat exchanger.

[0035] In this embodiment, the temperature increasing module B includes a resistance wire disposed in a vehicle-mounted liquid storage container, the resistance wire is electrically connected to a power source provided by a vehicle power source, and the liquid is heated by energizing the resistance wire. The principle of resistance wire heating is based on the heat generated when current passes through the resistance wire. When current passes through a conductor with resistance, the current will do work, resulting in the conversion of electrical energy into thermal energy. The thermal energy generated by the resistance wire is used to heat the liquid. This heating method has a high heating efficiency and a fast liquid heating rate.

[0036] In this embodiment, the preset threshold value is ≥ 10° C. By setting the preset threshold value, the corresponding heating module can be reasonably selected according to the needs, and the liquid heating rate can be increased while achieving energy saving to meet the different needs of users.

[0037] The energy-saving vehicle-mounted liquid rapid heating method provided in this embodiment is that the temperature control module calculates and compares the difference between the actual temperature a of the liquid and the heating temperature b expected by the driver and the preset threshold value, and outputs a heating instruction to the heating module A or the heating module B; the heating module A uses the thermal energy of the vehicle to heat the liquid, saving the power energy of the vehicle; although the heating module B uses the power energy of the vehicle to heat the liquid, the heating speed is fast, the scheme is simple to operate, and the temperature rise speed is fast, which can improve the vehicle experience and happiness to a certain extent. Therefore, this embodiment can alleviate the problem that the existing heated cup holder cannot heat the vehicle-mounted liquid to 100° and the problem that the existing heated cup holder consumes the vehicle's power energy for insulation and heating. Compared with the existing heated cup holder, it reduces energy consumption and improves practicality and user experience.

[0038] Example 2

[0039] In a typical embodiment of the present invention, an energy-saving vehicle-mounted liquid rapid heating system is provided, such as Figure 2 As shown, it includes an inlet module, a storage module, a temperature control module, a heating module and an outlet module; the inlet module is installed on the storage module, the inlet module is used to dock with the liquid storage container, and the storage module is used to store liquid; the temperature control module controls the temperature of the liquid; the heating module includes a heating A module and a heating B module, the heating A module uses the heat of the vehicle engine, or the heat absorbed by the vehicle from sunlight, and the heating B module uses the heat from the vehicle power source to heat the resistance wire; the outlet module is used to discharge the heated liquid.

[0040] In this embodiment, the inlet module is made of soft rubber material and has a certain degree of elasticity. The inlet module can be adjusted according to the size of the inlet of the beverage bottle, and can be changed according to the lids of different liquid storage containers. The inlet module and the lid of the liquid storage container can be tightly connected to allow liquid to pass through the inlet and enter the storage module. All beverage bottles on the market can be firmly connected through its inlet, allowing liquid to smoothly enter the storage module.

[0041] In this embodiment, the temperature control module includes a thermometer, a controller and a display screen. The thermometer is used to measure the temperature of the liquid and display the temperature in real time on the display screen. The controller is used to output temperature rise instructions to the temperature rise A module and the temperature rise B module. The set temperature and liquid remaining amount are also displayed on the display screen.

[0042] Furthermore, the heating module A controls the heat energy of the vehicle to heat the liquid by receiving the heating instruction of the temperature control module; optionally, the heating module A controls the heat of the vehicle engine, and does not directly use the power energy of the vehicle to achieve the purpose of energy saving; optionally, the heating module A controls the heat energy absorbed by the vehicle from the sun, and does not directly use the power energy of the vehicle to achieve the purpose of energy saving. The heating module B controls the resistance wire of the vehicle to heat the liquid by receiving the heating instruction of the temperature control module; optionally, the heating module B can use the power energy of the vehicle to heat the resistance wire, which has high energy consumption but fast heating.

[0043] Specifically, the heating module A uses the engine coolant circulation system for heating; the engine coolant and the liquid to be heated are heat exchanged in the heat exchanger. There are many small channels inside the heat exchanger. The coolant and the liquid to be heated flow in their respective channels and transfer heat through the tube wall. Alternatively, the heating module A uses a small solar collector to heat the liquid. The solar collector consists of a transparent cover, a heat absorbing plate, an insulation layer and an outer shell. The transparent cover allows sunlight to penetrate into the collector. The heat absorbing plate is usually a metal plate coated with a selective absorption coating. It can efficiently absorb the energy of sunlight and convert it into heat energy. The insulation layer reduces the loss of heat to the outside, and the outer shell plays a protective and supporting role. The liquid flows in the pipe inside the heat absorbing plate. The heat of the sunlight absorbed by the heat absorbing plate is transferred to the heat exchange medium in the pipe through heat conduction. The heat exchange medium provides heat to the liquid to be heated through the heat exchanger, thereby achieving the heating of the liquid. Those skilled in the art can select the heating method of the heating module A as needed, and can set the structure and connection method of the heating module A according to common knowledge, as long as the heat of the heating module A does not come from the vehicle power energy.

[0044] In this embodiment, the storage module adopts a transparent container, which can directly reflect the current liquid remaining in the storage container, or a liquid remaining detection instrument is provided in the storage module, which can provide real-time feedback of the liquid remaining on the display screen, and can feed back the liquid remaining in the storage module to the driver and passengers, so that the driver and passengers can replenish the liquid appropriately.

[0045] In this embodiment, the outlet module includes a micro pump and a water outlet, and the micro pump adjusts the speed of liquid outflow by adjusting the liquid pressure.

[0046] Optionally, the outlet module can control the outflow rate of the liquid by adjusting the size, shape and other parameters of the outlet. Specifically, an existing nozzle or nozzle with adjustable aperture size can be used; the nozzle can change the aperture size of the nozzle outlet through an existing mechanical adjustment structure. This nozzle is usually composed of multiple movable parts, and by rotating or sliding these parts, the nozzle outlet can form an outlet of different sizes such as a circle, ellipse or fan shape.

[0047] Optionally, the outlet module can control the outflow rate of the liquid by selecting a suitable pressure through the display interface. For example, an existing pressure regulating valve is used, and an electric pressure regulating valve is taken as an example. It is composed of an electric actuator and a regulating valve core. The electric actuator drives the valve core to move according to the received control signal (such as a signal from a sensor or a controller). The shape of the valve core and the matching design of the valve seat enable different pressure controls to be achieved at different openings.

[0048] The working process of the energy-saving vehicle-mounted liquid rapid heating system provided in this embodiment is as follows: Figure 3 As shown, the inlet module adjusts the size, shape and other parameters of the inlet, and is mainly used to connect the mouth cover of the liquid storage container. It can match all the beverage bottle caps on the market to meet the diverse needs of drivers and passengers; the storage module detects the remaining liquid in the module and promptly feeds back to the driver and passengers so that they can judge whether liquid needs to be added; the temperature control module detects the actual temperature a of the liquid in the storage module, and can also allow the driver and passengers to set their desired heating temperature b. By comparing the difference between the actual temperature a and the heating temperature b with the set preset threshold, the liquid heating instruction is output to the corresponding heating module; the heating A module controls the heat energy generated by the vehicle according to the received heating instruction and executes the liquid heating action; the heating B module controls the power supply of the resistance wire according to the received heating instruction and executes the liquid heating action; the outlet module allows the driver and passengers to select a suitable liquid outflow rate and controls the outflow of the liquid according to the selected flow rate.
